An enthralling week of cricketing action goes past us with a double-header Sunday delivering on the promise. Debutant Ishan Kishan stole the headlines with a blitzkrieg against England. The southpaw scored 56 off just 32 balls as he saw an increase of nearly 7%. He was well complemented by Virat Kohli, who himself achieved a fantasy price increase of 11%. None of the England batsmen or bowlers was able to assert themselves, leading to a disappointing loss. As for the other international game, West Indies completed a whitewash over the Sri Lankan with Shai Hope coming up with the goods yet again. The West Indian smashed his third fifty-plus score of the series, with Kieron Pollard applying the finishing touches towards the end!As the new week presents more opportunities for fantasy shareholders in the Market, a brief look into the past week's best performers. Without further ado, here are the Bulls and Bears of the Week!BULLS: Jason Roy (England) and Shai Hope (West Indies)Albeit in different formats, both Roy and Hope have seen similar increases (nearly 21% each) in the Sixer Market! Shai Hope has been absolutely sensational in the ODI format off late, but this series has seen him excel like no other player. With three 50+ match scores and a match score average over 80, Hope has been one of the most sought-after commodities in the Sixer Market! On the other hand, Roy has been England's best batter so far, with two handy knocks at the top of the order. While there were some doubts over his form, and especially with Alex Hales' inclusion being talked off regularly, the pressure was on Roy. However, the English ace delivered with a match score average of 92.13, which might have just cleared all doubts surrounding his place. As for his place as a Bull in the Sixer Market, there is no doubt whatsoever and he might even garner more trades given his fantasy stock price of 57.80 Sixer Coins per Share!BEARS: Jos Buttler (England) and KL Rahul (India)Jos Buttler and KL Rahul have been two of the best batsmen in the T20I format over the last few years. While Buttler has seen a resurgence in the opening slot, Rahul came into this series with a vote of confidence from captain Kohli regarding his place in the side. However, both of them have failed, with Rahul's decline being the harder pill to swallow. Rahul could only manage a match score average of 11.36 as he couldn't buy a run in both games. As a result, he saw a decrease of 17.96%, with his fantasy price at 47.50 Sixer Coins per Share! His counterpart Buttler couldn't get going at all with only a match score average of 33.87. However, both Rahul and Buttler can destroy bowling attacks like no other player and shouldn't be discarded this early into the series. But will they be able to conjure up some form before the IPL? Only time will tell!
